Stoker smoking pipe



Patented June 25, 1946 UNITED STATES PATENT OFFICE STOKER SMOKING PIPE Thayne Robertson, Boise, Idaho Application May 7, 1945, Serial No. 592,327

.t 1 Claim. l

This invention relates to pipes of the magazine type, wherein provision is made for holding tobacco in a magazine or container apart from the bowl where the tobacco is consumed by combustion or through the process of smoking, and an object of the invention is to produce a pipe oi' this character having novel means for transferring the tobacco from the magazine to the smoking bowl, which means may be manipulated from a location convenient to the smoker.

It is a further object of the invention to produce a pipe of this character which can be kept free of accumulated moisture which so often fouls pipes of this character.

It is a still further object of the invention to provide a magazine pipe of the character indicated in which the cover of the magazine has a humidor attachment, whereby the contents of the bowl is kept moistso that tobacco is in good condition for smoking.

It is furthermore an object of the inventio to produce a pipe of the character indicated comprising comparatively few inexpensive parts, efficient and satisfactory in use.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawing forming part of this application, wherein like characters denote corresponding parts in the several views, and in which:

Figure 1 illustrates a view in side elevation of a pipe embodying the invention;

Figure 2 illustrates a sectional view on the line 2-2 of Fig. 1;

Figure 3 illustrates a sectional view of the pipe on the line 3-3 of Fig. 2;

Figure 4 illustrates a sectional view of the pipe on the line 4--4 of Fig. 3 and Figure 5 illustrates a sectional view of the pipe on the line 5--5 of` Fig. 3.

In this drawing 6 denotes the tobacco reservoir, I the bowl and 8 the base of the structure, which are preferably integral. The base has a 'seat 9 into which a stem I0 is fitted and these tion I3 between the reservoir and bowl, and said aperture is occupied by a conveyor worm I4 having a trunnion I5 at one end which is seated in the inner wall of the bowl, and the said conveyor worm has a trunnion or shaft I6 at its opposite end which is rotatably mounted in a plug or bearing II which is seated in the wall of the reservoir. This bearing is shown as threaded in the wall of the reservoir, and the conveyor worm is thus held in operative relation to the reservoir and bowl and when rotated acts as a stoker for transferring tobacco from the reservoir to the bowl to maintain the supply of tobacco in the bowl, while at the same time stirring or agitating the said tobacco to an extent that free combustion is afforded when air is drawn through the bowl during the process of smoking.

The trunnion or shaft I6 is preferably provided with a knurled disk or wheel I3 by which the shaft and the stoker are rotated so that by the arrangement the draft is directly through the bowl to the stem, and since the worm is lled with tobacco, there is no back draft into the reservoir.

The cover I9 of the reservoir may be threaded in place or it may be fitted by a friction joint between them, and furthermore the cover has a cavity or recess 20 into which absorbent material 2l may be lodged, which material when saturated with liquid will serve to maintain the tobacco in the reservoir in a moist state and, under certain conditions, this absorbent material may contain a avoring element which is sometimes used in imparting quality to smoking tobacco.

It is shown that the stoker assembly may be readily removed for cleaning the pipe or for other purposes, since the bearing of the worm shaft is removably applied and the trunnioned end of the worm is displaceable axially to disengage it from the bowl.

I claim:

A pipe comprising a bowl and a, reservoir in communication one with the other, a tobacco feeding stoker comprising a conveyor worm rotatably mounted in the bottom of the bowl 4and reservoir, the said conveyor worm having a trunnion at one end rotatably mounted in the Wall of the bowl, a shaft at the opposite end of the said conveyor worm, a bearing in the wall of the reservoir in which the shaft is rotatable, an operating disk on the outer end of the shaft, a cover for the reservoir, the said pipe having a suitable smoke duct leading from the bowl, and a stem connected to the smoke duct.
